BOPDs started off by reflecting about multiplication using two dogs and a target. Breaking into groups, students then shared their ideas. There were a couple of big ideas that popped up through this exercise. One was that multiplication and division are inverse operations. Another was that multiplication was repeated addition. Armed with these thoughts, students paired up and solved a one-digit by one-digit multiplication word problems. As they began, they used talk moves. These equip us with a way to start a sentence and allows us to focus on explaining our thinking to someone else and considering our partner's thinking too, as stated in mathematical practice number three. Our goal is to state and explain our strategies to show different ways in solving problems.
